Nathan and Raizy Glauber, both 21 and Orthodox Jews, were using a car service to go to the hospital when another vehicle crashed into the side of theirs at an intersection in the Williamsburg neighborhood of Brooklyn, Hasidic community activist and family friend Isaac Abraham said.

Nathan Glauber was pronounced dead at Beth Israel Hospital, while his wife died at Bellevue, the New York Post and The Associated Press reported.

The couple's son was delivered at the scene and was taken to a hospital in serious condition, said Abraham, who is also a neighbor of Raizy Glauber's parents and lives two blocks from the scene of the crash.

Abraham said: "The child is in a serious condition in Beth Israel Hospital, in Manhattan. Now we just pray with the child that all medical efforts keep him alive."
